Tainted blood

I had an appointment to give blood today. I hate giving blood, as I am afraid of needles. But I understand the importance of it, and used to do it fairly regularly. However, it's been about 3 years since my last donation.

Unfortunately, when I went in today, I was turned around because I had been in Costa Rica within the last year. The funny thing is that the state/province/area in Costa Rica marked as dangerous is where we stayed in the Four Seasons, which was probably as sanitary and clean as Costa Rica gets. The area where we stayed literally in the rain forest was not on their list of dangerous places.

But they invited me back in September, when my year is up.
